Authenticates a member and returns an HTTP-only authentication cookie

This method of authentication is recommended for clients that do not have access to secure storage, as the authentication token is stored in a secure HTTP-only cookie.

Providing this cookie with subsequent requests works as an alternative to the LoyaltySessionToken HTTP header.

Sign out is handled by the ExpireAuthenticationCookie method.

When using cookie-based authentication, the API will automatically refresh the cookie when the access token has expired.

In addition to the authentication cookie, a second vista-loyalty-member-is-authenticated cookie is returned that can be used by the client to detect whether the patron is authenticated.

Data is to be provided as application/x-www-form-urlencoded form parameters in the format of member authentication request

Currently, the external_issuer grant type will fail if the provided external authentication token can not be linked to a single Loyalty member, and as such is unsuitable for social sign in flows.
